Enclosure Design
ROCBIT 2, 2.5" Portable Enclosure Design How does the Rugged ROCBIT 2, 2.5” Enclosures Design Help Protect Your Hard Drive? The safety-centric mechanical design of Rocbit 2, 2.5” enclosures provides critical hardware protection features including:
Secure Fixing MechanismThe auto-limiting segmented screws prevent damage to the hard drive due to over-tightening. The full-length bridgeboard provides additional protection by supporting the entire length of the hard drive. Integral rails hold the hard drive chassis firmly in place eliminating stress on the bridgeboard and preventing damage due to impact or violent movement.
Anti-Shock ProtectionThe Anti-shock damper strip between the bridgeboard and the chassis offers additional resistance against accidental drops and bumps. The disposition of the hard drive and housing profile form an anti-shock chamber to cushion the blow of potential impacts. |
| |
 |
| |
Easy Installation The Rocbit2, 2.5” enclosures eliminates connection hassles by with a high profile IDE connector, enabling level insertion of the hard drive and providing a larger connection target.Copper pillar reinforced screw guides on the front and rear panels stand up to wear and tear caused by frequent drive swapping.
Thermal Protection and load-bearing caseThe precision density of the rugged aluminum case provides excellent heat dissipation and is strong enough to bear external weight. |
| |
 |
| |
Error-proof Secure Key DesignThe Secure Key design is based on the FireWire 400 form factor. To eliminate potential confusion, the Secure Key employs a discreet error-proof module that can only be accommodated by the corresponding receptacle on the enclosure, thereby preventing potential damage to the FireWire port. |

Encryption Technology
How does ROCBIT Encrypted External Hard Drives Protect Your Data: Q: What security technology do Rocbit External Hard Drive adopt? A: Several security schemes are popularly employed to protect data including:
Password Security – This basic OS/Software solution blocks unauthorized data access by requiring a password. While this may be adequate for a coffee break, this form of security is very easy to bypass.
Biometric Security – This form of security requires a combination of a unique physical characteristic, such as a fingerprint, retinal scan or vocal signature. While more secure than simple password security, it can be circumvented too, leaving unencrypted data at risk. Biometric security also requires a substantial hardware investment and additional administrative burden.
Hardware Security – Hardware Security is by far the most thorough, cost-effective, and easily implemented form of advanced security. Rocsecure – Rocbit external Drives use Hardware base Security, performed by eNova’s X-Wall ASIC, to provide reliable security for your stored data. Every bit and byte on the hard drive is strongly encrypted by DES (Data Encryption Standard) or TDES (Triple DES) algorithms. There is no possibility that clear text will remain on the hard drive. Q: What is Hardware Based encryption? A: Encryption is a sophisticated mathematical calculation (or algorithm) combining a “Secret Key” and clear text. The resulting “cipher text” is an unreadable code that can only be decrypted with the original “Secret Key”. The hardware encryption, performed by eNova X-Wall® microchip, delivers significant performance improvement over software encryption, works with every operating system found today, and requires no additional training to use. This encryption methodology protects your valuable data with minimum Total Cost of Ownership (TCO).
Q: What does encryption function? A: X-Wall LX ASIC sits between the PCI Bridge and the device on the IDE interface. It intercepts, interprets, translates, and relays REAL-TIME, IDE commands and data to and from the disk drives, encrypting the data with DES (40-bit or 64-bit) /TDES (128-bit or192-bit) key strength. The following illustration best describes how the security chipset functions. |

Q: What is the Secure Key and why use it?  A: The Secure Key is a physical key that contains the “secret key” necessary for encryption and decryption operations. The hard drive must be partitioned and formatted using the Secure Key the first time the hard drive is used. When complete, the entire content of the hard drive is associated with the unique Secure Key. Only a Secure Key containing the identical “secret key” can be used for authentication and decryption of the hard drive at power up.
The Rocsecure Key design is based on the FireWire 400 form factor. To eliminate potential confusion, the Secure Key employs a discreet error-proof module* that can only be accommodated by the corresponding key receptacle on the enclosure, thereby preventing potential damage to the FireWire port. Note: Taiwan Patent No. M253038 Q: Do I need to establish a separate “encrypted folder” under file directory as required by some software solutions? A: No. Everything you write to the disk drive is automatically strongly encrypted. There is no need to establish a separate “encrypted folder.” Q: Does X-Wall LX increase the original file size after encryption? A: No. DES/TDES is a complicated mathematical algorithm that computes the original data with 40/64/128/192-bit key length. Regardless of the size of the encryption key, the size of data file after encryption remains unchanged.
Q: Are Rocbit encrypted Drives compatible with all disk drive types? A: ROCBIT encrypted Hard Drives are compatible with Ultra ATA (Ultra DMA) 66/100/133 compliant disk drives in real-time performance with throughput of 1.6 Gigabits per second.
Q: Can Rocbit External Drives work with any operating system? A: Rocbit External Drives require no device drivers and are independent from all operating systems. A host controller with a USB/1394 mass storage driver typically provided by the OS is required. The only requirement is an Ultra ATA (Ultra DMA) compliant disk drive.
Q: Do Rocbit Drives support 48-bit LBA addressing?
A: In general, a larger key length creates a stronger cipher, which means an eavesdropper must spend more time and resources to find the decryption key. For instance, 240 (DES 40-bit strength) represents a key space of 1,099,511,627,776 possible combinations. While this number seems impressive, it is definitely feasible for a microprocessor or a specially designed ASIC to perform the huge number of calculations necessary to derive the key. Thus a 40-bit length cipher offers the bare minimum of protection for your confidentiality and privacy. The “work factor” increases exponentially as the key length is increased. For example, an increase of one bit in length doubles the key space, so 241 represents key space of 2,199,023,255,552 possible combinations. A 2112 bit (128-bit) TDES cipher offers extremely strong security
(5,192,296,858,534,827,628,530,496,329,220,096 possible combinations) projected to be capable of resisting that should resist known attacks for the next 15 to 20 years, considering the advance of semiconductor design and manufacturing. Q: How do I know my ROCBIT Encrypted External Drives are really secured? A: The DES/TDES hardware engine utilized by X-Wall LX has been certified by the NIST (National Institute of Standards and Technology) and CSE (The Canadian Security Establishment). To review these certificates, visit the following NIST web links:
http://csrc.nist.gov/cryptval/des/desval.html and http://csrc.nist.gov/cryptval/des/tripledesval.html . These hardware algorithms are certified to provide reliable security; at full strength it is virtually impossible to access the encrypted data by guessing or deriving the right DES/TDES Key. Because everything on the disk is encrypted, your data is safe even if attackers try to boot from their own disk, or to move your disk to an unprotected machine.
Q: Can I remove the Secure Key while my PC is on? A: Yes, you can remove the Secure Key for safekeeping after your operating system has fully loaded. Remember that the Secure Key MUST be used again the next time you power up your system.Note: The above X-WALL ASIC product information is property of eNova and is provided for informational purposes only. eNova retains copyright and ownership of all provided material regarding the eNova X-WALL ASIC.
